SANITARY rLusn BOWL.

Application filed. May 8, 1919.

To all whom it may concern:

Be it known that I, ALEXANDER D. GRANT, a citizen of the United States, residing at San Jose,,in the county of Santa Clara and State of California, have invented new and useful improvements in Sanitary l lush Bowls, of which the following is a specification.

This invention relates to a sanitary flush bowl.

It is the principal object of the present invention to provide means for supplying a disinfecting solution to the bowls of commodes or urinals, said supply operation being automatic with the flushing operation and further insuring that the chemicals used for disinfecting purposes will be maintained in a desirable condition. Heretofore, it has been common to provide flushing devices fitted with disinfectant-supply means, but in most instances these devices have only operated when the bowl was being flushed and thereafter completely exposed the chemicals to the action of the air, thus causing them to rapidly deteriorate and to render the disinfectant inert. It is one of the principal objects of this invention, therefore, to

provide a container for the chemical which will insure that it will be protected from the action of the air at all times, and will at the same time be freely exposed when the bowl is being flushed.

The present invention contemplates the use of a container disposed in close proximity to the flow of water by which the bowl is flushed and which container is supplied with suitable disinfecting; chemicals over which a portion of the water flowing to the bowl will pass and by which a disinfecting agent will be mixed withthis water to flow to the bowl and produce a disinfecting and sanitary result.

The invention is illustrated by way of example in the accompanying drawings, in which;

Fig. 1 is a central vertical section showing a commode with the sanitary flushing device formed integral therewith.

Fig. 2 is a view in section and elevation illustrating the commode and more clearly disclosing the manner of circulation of the flushing liquid.

nals, and which is also capable of being used as an attachment for either urinals or commodes.

Fig. 4 is a sectional view in plan, showing the use of two chemical containers.

Referring more particularly to the drawings, 10 indicates the bowl of a commode. This bowl is of any preferred design and is here shown as having a front baffle wall 11, which forms a passageway 12 in the bottom of the bowl. The passageway 12 leads up wardly and over a lip at the forward end of the bowl to thereafter continue in a vertical passageway 13, thus providing a syphon. The vertical passageway 13 communicates with an outlet of passage 14 leading to the sewer. The supply of water to the bowl 10 is permitted due to a provision of a plurality of inlet openings 15 formed around the upper lip of the bowl and inlet opening 16 formed at the back of the bowl and between the face of the bowl and an upper bafiie wall 17. Directly in the rear of the inlet 16 is a sanitary drain duct 18, through which an after-flow of water will take place and by which it will be insured that a certain quantity of water will always stand in the bottom of the bowl 10. The inflow of water is conducted to the openings 16, 16 and 15 through a passageway 20. The'upper end of this passageway is fitted with any sort of a supply pipe 21 leading from a flush tank or directly connected with the supply main. As shown in Fig. 1, the foward and upper wall of the passageway 20 forms one wall of a compartment 22. This compartment is provided to receive a disinfectant and to permit a certain circulation of water over a body of chemicals as indicated by 23.

The circulation through the chamber 22 is established through an inlet duct 24 formed in one side of the chamber and in communication with the passageway 20. In order to insure that a suitable quantity of water will be diverted into the chamber 22, a baflie ridge 25 is formed in the outer side wall of the passageway 20 and in horizontal alignment with the opening 24. The opening 24 is here shown as inclining downwardly and into the chamber 22. This passageway is here spaced substantially midway the height of the chamber 22 and above the level of the chemicals as indicated by the member 23. Directly opposite the passageway 24 in the wall 26 of the chamber 22 is an outlet duct 27. This duct is inclined ontwardly and upwardly and through it the liquid flows from the chamber into a supply passage 28. The supply passage has an outlet 29 in its floor and thus allows the liquid to drain down and to comingle with the uncontaminated water passing directly through the passageway 20 and to the openings 15, 16 and 18. In order to prevent a seal in the chamber 22 an air-vent opening 81 is provided. This vent is in the wall. 26 and near the top of the tank. The chamber 22 has a filling opening 32 in its head and this opening is adapted to be closed by a threaded stopper or a smooth tapered stopper as shown at 33.

In the form of the device shown in Fig. 3, a chamber 22 is formed integral with a casing 341.. This casing may be embodied in the construction of a urinal or it may be used as an attachment for either urinals or toilet bowls. The casing 22 has an outlet 35 in its side wall, and an inlet 36 in its upper wall. The upper and side walls reterred to are surrounded by a water passageway 37, which is supplied with water to an upper pipe 38 and from which the water is' drained to an outlet pipe 39.

In operation of the present invention the pipe 2-1 is supplied with water, either directly from the mains or through a flushing mechanism as desired. lnthe form of the device shown in Fig. 1, this water will flow downwardly into the passageway 20 and strike the baffle ridge This will cause a certain portion of the water to be deflected and directed through the duct 241-.

It will be understood that while the duct 2% hasbeen described as being a single opening and the opening 27 as a single opening that it is within the spirit of the present invention to provide a plurality of ducts in horizontal alignment and a plurality of openings 27 in similar alignment. These latter openings corresponding to the number of drain passageways 29 in the floor of? the passage 28. In any event it is desirable to design the chamber 22 with adequate ducts both for inflow and outflow to thereby insure a desired flow or circulation of water through the chamber 22 and over the body of chemicals contained therein. When the water passes into the duct 2ft it will pass over the chemicals and will be contaminated thereby. It will thereatter pass outwardly through the duct '22 and down into the bowl of the toilet through the drain opening 29. Here it will mix with the clear water and will be distributed through the various compartments of the bowl. In View of the fact that water inflowing from pipe 21 will be under pressure, the water will fill the compartment 22 more rapidly than it will drain therefrom, and for that reason there will be an afterflow of the disinfecting fluid from the com partment 22 after the passageway 20 has been drained of the clear water. This afterflow will pass through the drain opening 29 and fall into the enlarged mouth portion of the passageway 18, wiere it will be conducted to the bottom ol the toilet bowl and will. thus insure that under normal conditions at disinfecting solution will at all times be in the toilet bowl.

In operation of the form of the device shown in Fig. 3, the inflowin water will strike the upper horizontal wall of the compartment 22 and will force its way through the perforations 36 in the top of this wall, to thereafter mix with the chemicals in the chamber 22 and How outwardly to the drain opening 85. In the operation of either torm of the device shown in the present drawing it will be noted that after the water has drained from the chamber 22, a suiiicient amount of water will stand over the top of the chemicals and will thus be sure that the chemicals will besealed and protected against any action of the atmosphere. At the same time this'will make certain that a certain amount of disinfectant will be in solution within the container and will be readily mixed with the fresh' water flowing therethrough.

lit may prove desirable to provide two containers as indicated in Fig. 4:, each of said containers to carry different solid soluble disinfectants. This will make it possible for two chemicals to be held out of 0 contact with each other. and to be thrown together in the water to perform a desired chemical action and to produce a desired disinfectant.

While it have shown the firm form of my 5 invention as now known to me, it willbe understood that various changes in the combination, construction. and arrangement of parts may be made by those skilled in the art without departing from the spirit of 1 my invention as claimed.

l laving thus described my invention, what I. claim and desire to secure by Letters Patent is: e v
